The drying temperature of drying equipment has multiple impacts on materials, which directly affect the quality and production efficiency of products. The following is a detailed analysis of these impacts:
1、 The impact on the physicochemical properties of substances
Burnt or deteriorated:
Excessive drying temperature may lead to material burning or deterioration, especially in thermosensitive materials. Charred products not only have poor appearance, but may also affect their physical and chemical properties and activity.
Color change:
Some materials may undergo color changes such as oxidation and browning at high temperatures, which can affect the appearance and quality of the product.
Active destruction:
High temperature may damage the activity of active ingredients in materials, leading to a decrease in product quality.
2、 The impact on drying efficiency
Accelerate water evaporation:
In general, higher drying temperatures can accelerate the evaporation of water, thereby improving drying efficiency.
Surface hardening:
However, excessively high temperatures can cause the surface of the material to harden too quickly, which in turn hinders the diffusion of internal moisture and reduces drying efficiency. Especially in the process of spray drying, too high temperature will lead to surface hardening of droplets, increasing the risk of wall sticking.
3、 The impact on product recycling rate
Incomplete drying:
Low drying temperature may result in insufficient drying of materials, thereby affecting product recovery rate. Products with high moisture content may not meet quality standards and need to be removed or reprocessed.
Excessive drying:
Excessive drying temperature may lead to over drying of materials, resulting in quality loss. Products that are excessively dry may become fragile, brittle, or crack, thereby affecting their integrity and ultimate use.
4、 Impact on equipment
Equipment aging:
Long term operation at high temperatures can accelerate equipment aging and wear, and vulnerable parts such as bearings and seals may fail due to high temperatures.
Increased energy consumption:
To maintain a high temperature environment, more energy needs to be consumed, which not only increases production costs but may also have a negative impact on the environment.
5、 Impact on operational safety
Fire risk:
Excessive temperature may cause safety accidents such as fires or explosions, especially when dealing with flammable and explosive materials.
Personnel injury:
High temperature environments may pose a threat to the health of operators, such as burns, heatstroke, etc.
In summary, the drying temperature of drying equipment has multiple impacts on materials, including their physical and chemical properties, drying efficiency, product recovery rate, equipment lifespan, and operational safety. Therefore, in practical operation, the drying temperature should be set reasonably based on factors such as the properties of the materials, drying requirements, and equipment performance to ensure product quality and production efficiency while ensuring the safe operation of the equipment and the health of the operators.
